My invention relatestoa mechanism for use in filling bottles with carbonated or charged liquids, its object being to provide 2 such a mechanism as to make repairs and re.- placements of parts thereof possible WIt hOHt 4 its completeremoval from the tank contain ing the liquid. I 1 My invention is appliedto and used in coming mechanism, the principles of which are shown'in Patents Nos. 948,463, and 956,867, and Reissue No. 13,197 and comprised in the accompanying drawings, Figurel.

Figure 1 is a sectional view of the complete counter-pressure mechanism comprising my invention. Figure 2 is an enlarged frag mentary sectional view of the liquid valve showing the features of my invention in die-- I, tail. Figure 3 is a plan view taken on llne 2o 11 of Figure 1. y I

Referring to Figure 1, 1 designates the intermediate body of the filling mechanism, which is secured in an opening 2 in the bottom I, of the liquid tank 3 by bolts, or other means, '25

the washer or gasket 4 being compressed against said tank around said opening and preventing leakage therefrom, with the verti cal member extended upward through said opening 2 into said tank and above the level 5 of the liquid therein, as shown. 1

features of my invention shoWn in Figure 2 and Figure 3 and hereinafter described) is a the usual typeof counterpressure bottle filling mechanism, and is explained as follows. The liquid tank 3 is air tight to confine a certain degree of pressure therein, as required, and this pressure acts upon the diaphragm 6 to force it upward and by means of the connecting rod 7 attached thereto at 8 holds the liquid valve head 9 normally seated tightin' and against the lower end ofthe filling tube 10. Passage of the charged'liquid from the tank 3 through the passage 1111 and downthereby prevented.

, The counterpressure chamber-12 is nor-v mallyopen-to the atmosphere through passages connecting therewith the two tubular supports 13, which register with passages 13' binati on with the usual counter pressure fill-- "Said filling mechanlsm (excepting for ther wardly out through the filling tube 10lis:

in the body member {1, passages connecting said: tubular membfsi'with theair chamber} 14:, and passage 15.j-15.,-1'said I atmosphericpressure being 'overbalanced by the pressure. in the tank with the resulting upward movedescribed. 7 y a i l 1 v When a bottle is put in the filling position in the centering bell 16, slidably 7 arranged on the filling tube 10 and pu h upwar 3 the head thereof 17 is pushed against and unment of the diaphragm as ,hereinbefore seats the air valve 18; This admits pressure furnished through the air inlet passage 19-49, through the lateral ports 20, passage 15 andqpa'ssages in the centering bell head 17 registering with said passage 15', to

the bottle, and 'atvthe same time through the, passage 15, air chamber 14:, and air passages to thejubular'supports and connecting i ir: P a e the chamber 12. e

When the P e. in v the chamber 12 equalized'. with or made greater than the pres;

sure below the diaphragm, theliquid valve;

9 will be opened either by gravity or thep-res- X sure 'above'the diaphragm, the counterpressure having'been established in the. bottle; The liquid valve is opened by the same pressure that is admitted to the bottle, andflas I this occurs when I the counterpressurel has been fully established in the bottle the liquid will flow into the bottle without loss of' gas or production of foam; .I

When the bottle is removed the air valve 9 is seated and-the air inlet 19" closed by the air valve 18, saidair valve being "actuated and kept'normally seated by;the spring; 32' inthe air chamber 14. The pressure in chamber 12, isther'eby eliminated and ithe;pressure from theli'quid tank closes the; liquidrvialve.

9 in the manner hereinbefore described. v ,The foregoing explains thefoperation of the ordinary counter-pressure. filling mecha f nism, andof which my'inventionis an im :provement. 1

I Heretofore, I when theliead of the valve'9, or the lower entrance to the filling tube 10 became worn and the mechanism,

leaked at-that point so thatreseatingof saidvalve wasrequired, or when any internaLrefpair to the filling mechanism below the ini onvenience and labor requlred to' perform the-removal and dismantlmg operatloni 11;. fitted; thereon inithezmanner shown; "The base of "said rod? is'threaded, and ajcap,

termediate body member 1 was found necessary, it was required that the entire filling mechanism, hereinbefore described and comprised in Figure 1,.be removed from the liquid tank' asthere was no means of disassembling the head of the liquid valve 9 from the connecting rod 7 both beingmade as a compact inseparable" unitl' This I condition made itimpossible'to remove any ofthe x m parts comprised in themechanism below the i able over the'point 21 on the filling tube, and the filling tube was not removableoverfthe:

body member 1 as said parts-were not remov V unremovable head 9 of the liquid valve.

' The only means offdisa'ssemblingthe V mechanism was the threaded connection of the connecting rod 7 with :the diaphragm at 8-581; 'But said unitaryrod and valve head could not 'be'dis'connected at'8 while said Inechanismwas attached to the without 3 allowing passage of the: liquid from thetank' through the entrance 11' to the filling tube and out of'said tube, and this could be'aec'omplishedon-lyat great inconvenience and dan-- ger' resulting'from theforce of the liquid re leased through the tube 10. s

' Accordingly, the liquid tank had' to be emptied, with resultingloss of such charged liquid therein, and sothatthe complete mechanism'might be removed, with the attendant sothat'said repairs might be made.-

"My invention relates particularly to improvement in? said filling mechanism be ma in said tank;

V "Fi'gure2" shows the demountable valve feature of my invention, the liquid valve 9' being--rnade separate from "the rod? and 22 fitted thereon, said'cap" being either threaded or unitary with the connectingrod 7. The rod 7 is threaded atthe top at 8 l and screwedinto the sleeve8 so that it' may be adjusted up or down toprovide a tight seat for said valve 9 when normally'closed The liquid valve head 9 is fitted'over' said rod 7' and tight" against said cap,flthe locking ridge 23 holding it rigid and preventing leakage. Said head 9 is held in position on saidrod and against said cap 'bya base member 24 threaded and -securedon'said rod 7 tightly against said valve head 9.

Figure 3 illustrates the feature of vention'com-pnsing a valve 1n the intermediate member l'adaptedto close theentrance-11 am theliquid tankto'the filling tube-10. I

The means I have adopted to so close said entrance comprises the actuating or screw member 25 in combination with a movable member 26 within the recess 27 and chamber 28, said chamber having a removable cover 33, and kept leakproof at the base thereof by the gasket 34. The movable member 26 is fittedwith resilient packing material 29 on the forward endthereofi-such as rubber,

adaptedto fit or be compressed tightly over t e-passa e; and: arqu drihe downwardly extending rod 7 when actuated forward 'over said passageill and against acorresponding, portion 30 of said material on the opposite.

side-of said -rod 7, 'thereby completely closing the passage l l to the filling tube 10.- 'Said passage may be reopened by merely revers ing the aforesaid operation of the valve in] the body member 1.

' It will be noted from-Figure 1 that the means 25 actuating said movable member '26 may be reached easily whenthe filling mesh-1 7' anism is fastened to the liquid tank, and the supply of liquid from. said tank may be con veniently out off by the operation thereof.

' Vwien the passage 11 is so closed, with the removal by' unscrewing of the base portion 24 ofthe liquid-valve and removalsof' the head 9 thereof from the rod 7, the filling tube 10 which is threaded into the body member 1 at 31, all ,of the separate portions of the mechanism depending from the body meme-i l her 1, with the exception of said rod 7, may be dismantled and removed for whatever purpose required without removing-thesaid intermediate body member- '1 and upwardly extending members of the filling mechanism fromthe tank. The usual means of cutting.

off the pressure in the line connectingwithr air inlet 19, may be employed. My invention comprises? in principle a means in the body.member 1 of the filling mechanism for closing the'passage 11 to the" filling tube '10 and a demountable liquid valve at the base of said filling tube, said. valve being actuated by the operation of the diaphragm and connecting rod hereinbefore described, it being recognized that the means I have adapted theretomay be modified .or 7

improved upon to suit the individual. requirements' without departing from the scope of' my invention, for theosubjooined claims.
